Question

For the reaction 2NO + Cl2 --> 2NOCl Match the appropriate rate law to each postulated mechanism.

A Rate = k[NO][Cl2]2

B Rate = k[NO]

C Rate = k[NO]2[Cl2]

D Rate = k[NO]2[Cl2]2

E Rate = k[NO]2

F Rate = k[Cl2]2

G Rate = k[NO][Cl2]

H Rate = k[Cl2]

I None of the above

1. NO + Cl2 = NOCl + Cl slow

Cl + NO = NOCl fast

2. 2NO = N2O2 slow

N2O2 + Cl2 = 2NOCl fast

3 NO + Cl2 = NOCl2 fast equilibrium

. NOCl2 + NO = 2NOCl slow

4. NO + Cl2 = NOCl2 fast equilibrium

. 2NOCl2 = NOCl3 + NOCl slow

NOCl3 = NOCl + Cl2 fast

For 2NO + Cl2 --> 2NOCl

rate = C Rate = k[NO]2[Cl2]

and

3 NO + Cl2 = NOCl2 fast equilibrium

. NOCl2 + NO = 2NOCl slow
